DDS169 electronic single-phase electric meter

Product Description

DDS**9 electronic single-phase electric meter Application： 　　 DDS**9 Series electronic single-phase electric meter is the most advanced static electronic meter in ***** meter designs use large-scale integrated circuit, high reliability step motor, it can meter the AC single-phase active energy(voltage rating:**0V;frepuency *0Hz), positive and negative two directions and accumulates in one ***** on flash light, so it could be manged very easy. 　　The quality technical norm of the products is in accordance with the GB/T*********2 national standard and IEC****6 international standard. Principle： 　　 The meter samples the voltage and the current at the voltage divider bulit in the ***** samples are went to the amplifier and multiplier, output of the multiplier is processed by the integrated circuit V/F conversion, frepuency divider, power drive circuits to provide plus to drive step motor and mechanical register to accumulate custmer’s electrical energy consume. Technical indexes： High accuracy:error＜�1.0%1Class(＜�2.0%2class) High sensitivity:initial starting current ＜0.4%Ib Range of large load :current overload ratio＞6 The temperature range:The normal temperature of work:*****5 The extreme limit temperature: *****5 Low power consumption:consumption of meter itself ＜1W High reliabilty:MTBF＞**5 Weigh:＜0.6kg Starting current the meter can wok correctly at rated frequency, when load current is Larger than 0.4%Ib.(power factor:1), Running with no-load The meter use logic circuit to anti-creep.
